Abstract: Abstract of the Disclosure A voltage and frequency control circuit converts an alternating current input signal with inconstant frequency and voltage amplitude to an alternating current output signal with constant voltage amplitude and a constant nominal frequency which is lower than the lowest occurring frequency of the input signal.  An amplitude control circuit converts the input signal to an ac signal having constant voltage amplitude.  A rectifier circuit is regulated by an ac voltage source to provide positive half-cycles of the output signal from the amplitude control circuit during the positive half of the ac voltage source cycle and to provide negative half-cycles of the output signal during the negative half of the ac voltage source cycle.  A filter circuit smooths and shapes the output of the rectifier circuit to provide a sinusoidal output signal having constant voltage amplitude and constant frequency.  The amplitude control circuit, rectifier circuit and filter cir-cuit may be connected together in any order to achieve the desired output signal.  Also disclosed are variations which provide multiple output signals from a single input signal and a single output signal from multiple input signals.

Abstract: ADJUSTING DEVICE FOR HAT WITH SWEAT BAND    Abstract A hat having an adjustable sweat band for controlling the tightness of the fit of the hat.  A hat is provided with a sweat band of a flexible material having a draw strap secured at one end to the band and extending circumferentially of the sweat band on the side of the band adjacent the crown.  Cooperating fastening means at the free end of the strap and on the band are employed to adjustably locate the free end of the strap relative to the band so that the effective circumference of the sweat band, and thus the fit or size of the hat can be adjusted by a draw loop or drawstring arrangement which is shielded from contact with the wearer's head by the sweat band.  A strip of resilient padding which may be of a moisture absorbent material extends circumferentially of the sweat band between the strap and sweat band to provide a further cushion between the fastening means and the head of the wearer.

Abstract: ABSTRACT OF THE DISCLOSURE A casing suitable for covering a substantially rectangular electrode for a diaphragm-type electrolytic cell comprises a closed end, an open end, and two closed sides, at least one of the closed sides having a tab adjacent to the open end. The casing is formed of a flexible material which is folded or sealed to provide a closed end and then sealed to form two closed sides. The seal along a major portion of the sides is substantially linear while the seal along the edge of the tab is angular to and contiguous with the linear seal. The tabs, which can be twisted or turned to provide a flat surface, permit the casing to be easily sealed along the top and bottom edges to provide separa-tors for diaphragm-type electrolytic cells which are leak-proof and expand or contract during cell operation without detrimental mechanical stress.

Abstract: Abstract of the Disclosure In electron beam apparatus having a source of electrons and a target area toward which the electrons are directed, electron beam forming means are provided along the path from the source to the target.  These forming means include a first beam shaping member having a first spot shaping aperture therein, a second beam shaping member having a second spot shaping aperture therein, and means focusing the image of the first aperture in the plane of the second aperture to thereby form a composite spot shape defined by the image of the first aperture and the second aperture. Further means are provided for focusing the image of the composite spot in the target area.  Preferably, the apertures are square shaped.  Thus, by varying the position of the superimposed image of the first aperture with respect to the second aperture, a wide variety of rectangular shaped composite spots with different dimensions is obtainable.  This permits the exposure of rectilinear patterns, e.g., in photoresists of integrated circuit fabrication, by the electron beam with a minimum of exposure steps and substantially no exposure overlap. The result is greatly increased speed in the total exposure of such rectilinear areas to the electron beam as well as a minimum of the "blooming effects" produced by exposure over-lap.

Abstract: OPERATIONS VESSEL FOR ICE COVERED SEAS          ABSTRACT OF THE DISCLOSURE     A mobile monopod operations platform for use in ice covered seas and adapted for carrying out two modes of ice disaggregation, either or both such modes being selectively useable during either transit or relatively stationary operation.  An ice breaker bow is employed in conjunction with simulated pitching and heaving brought about by the programmed use of a plurality of fully      thrusters on a submersible hull.  At the stern of the monopod structure, counter-rotating cutting drums are utilized for ice disaggregation in a mode particularly useful when the ice is thick.  Topside of the bow and cutter area, an enclosed, generally circular, superstructure is provided for carrying out the requisite operations while mitigating the adverse effects of high winds.  The aforementioned fully azimuthing thrusters are available to facilitate both movement of the platform to a select operational position and to maintain stability during the required operations as well as to simulate the pitching and heaving motions required for bow breaking of the ice sheet.

Abstract: Abstract A joint-taping tool for wallboard (drywall), wherein there is almost no possibility that the cable will break after  the piston reaches the top of its stroke. and wherein the operator is immediately and unquestionably informed when adhesive flow ceases.  Furthermore, mechanism is pro-vided by which--with minimized action on the part of the operator-- the rollers are prevented from spinning and "throwing" adhesive (cement) during filling of the barrel.     The tool will not only apply tape and adhesive simultaneously, but is rapidly convertible to deposit ad-hesive over previously-applied tape.  This same conversion option makes it possible to eliminate tape jams quickly and easily.  In addition, means are provided for thoroughly cleaning the tool at the end of each day.
